Abstract

The present invention provides a broadband compact shaped array antenna, which includes N broadband microstrip antenna units, a one-way N-way stripline Wilkinson power distribution network and an assembly carrier, and adopts N broadband microstrip antennas designed with a multi-layer structure. The antenna units are arranged horizontally and equidistantly to form a line array, and one sub-N stripline Wilkinson power sub-network is placed horizontally and connected to N broadband microstrip antenna units through coaxial adapters for the realization of the line array The required shaping effect provides the corresponding excitation amplitude and phase. The one-point N-way stripline Wilkinson power distribution network adopts a multi-layer transfer interconnection structure design to reduce the three-dimensional occupied space and reduce the design cost. The assembly carrier is located in the antenna The layer and the feed network layer play a supporting role. By rationally designing the antenna unit, the excitation amplitude and phase, the feed network and the interconnection matching structure, the present invention realizes a wide frequency bandwidth, small three-dimensional space occupation, low side lobe, A broadband compact shaped array antenna with advantages of high gain and low cost.

Description

technical field [0001] The invention relates to the field of microwave antenna array design, in particular to a broadband compact shaped array antenna. [0002] technical background [0003] With the continuous upgrading of electronic countermeasures in military electronic warfare and the increase of civilian and commercial wireless communication capacity. A single antenna on an electronic device appears to be weak and lacking in the types of functions that can be realized, which makes the application of beamforming technology in array antennas and broadband array antennas an urgent problem to be solved. The array antenna must meet the requirements of the active standing wave ratio, the radiation gain of the antenna when it is transmitting, the radiation efficiency of the antenna when it is transmitting, and the radiation pattern that can be flexibly controlled in the working frequency band. In today's complex environment, traditional low-side lobe antennas cannot meet the s...
